unable to load apps

IPhone 4s, Evernote,Facebook apps not load
Hi currently on holiday,so have limited access and just basic wifi
Yesterday noticed phone was asking for several app updates so clicked for them to update anyway later tried to use Evernote, I am a premium user so needed to type in password.
Only one side of screen would accept input on keypad. Strange not happened before and not affecting anything else.
Typed in password wrong few times decided to re install, however now when installing get welcome message, in small screen and touchscreen not work
Also when opening the following apps get a small screen as well and can't proceed
Evernote,Dropbox,Facebook,Groupon.

IPhone running. 7.1.2 (11d257)
Any ideas anyone seen or heard of this
I've tried rebooting phone and re installing Evernote a few times but no good
Thanks
